Abstract: PURPOSE: A subdistricted apartment house heating system is provided to gather hot boiler water to a heating supply header, to transfer the boiler water to a heat exchanger by the heating supply header, to convert heating water, which is used at a used place, and to the heating water of predetermined temperature in the heat exchanger by heat-exchanging the used heating water again, thereby supplying to the used places, respectively. CONSTITUTION: A subdistricted apartment house heating system includes a hot water boiler, a heating supply header, a heat exchanger, a heating re-circulation header, a direct online start type heating re-circulation circulating pump, and a control unit. The heating supply header supplies the boiler water, which absorbs heat from heat source which is supplied from the hot water boiler, to each heat exchanger for heating. The heat exchanger exchanges the heat between the boiler water and the heating water, which are supplied from the heating supply header, and then supplies the heat to each used place through the heating pipe. The heating re-circulation header collects the boiler water, which is completed to heat-exchange in the heat exchanger, again. The inverter control type heating circulation pump forcibly transfers the low temperature heating water, which is used in each heat exchanger, to the heat exchanger again. The direct online start type heating re-circulation circulating pump forcibly transfers the boiler water, which is collected in the heating re-circulation header, to the heating boiler again.
